AM I PREGNANT!!!?? OPINIONS PLEASE!?

Okay so, i had sex with my boyfriend a day after my finished period (10th of june), we used a condom, but it broke and as soon as we noticed, we both pulled away (id say he was in me unprotected about 2 mins) lucky he wasnt near "finishing" I've heard that its not that possible to get pregnant on your infertile days, but am still a little worried because of the pre-eyaculation fluid (he pee'd before the sex). My cycles are almost always irregular. Usually around 30 to 38 days. I know their is always a possibility, but what are my chances. Please opinions.
